PATENT OFFICE CHAIR Hugo Melder, Mahn-Ostrau-Witkowuz, Czechoslovakia Application June 28, 1929, Serial No. 374,433 In Germany November 6, 1928 1 Claim. (cl. 155-50) This invention relates to a chair made from tubing of any kind, especially steel tubing, or from solid material, such as wood and the like and adapted particularly for use in motor cars, omnibuses, railroad cars, etc.

Chairs in which the seat and back form a unit resting on a separate support are known already, but they suffer from the drawback that they are not elastic. In other known types of chairs the back and seat are bent from a piece of tubing in one operation, which has "the effect that shocks are transmitted from the back to the seat and vice versa.

The invention eliminates these drawbacks by providing a chair, the seat of which is not in contact with the back, so that both the seat and the back can swing freely and independently of one another. Furthermore, the chair is designed so I as to render its production simple and cheap. To

attain the objects of the invention the chair is formed by a base including two spaced horizontal tubular members which are uniformly bent upwa'rdly in the rear so as to form a closed and freely swinging frame for the back while the front portions of; the base members are also bent up and thence extended in horizontal direction to form a support for the seat.

By way of example, the invention is illustrated in the accompanying drawing, in which a chair,

is shown in perspective. Referring to the drawing, the chair consists of a unitary tube made for instance-of a special steel. The base comprises two spaced horizontal tubular members 17, 17' which are bent up in front to form vertical supports 1, 1' which then extend laterally to form the side supports 9, 9' preferably connected at their ends by the member 10 and carrying the seat 3. The rear portions of the members 1'7, 1'7 are bent up also and form the side supports 4, 4' connected on top by the member 8 and carrying the covering 6 for the back. As indicated in the drawing, the side supports 9, 9' are united by the connecting part 10 and project between the-upwardly extending portions 4, 4' at a distance from the latter to be out of contact with them. In this way the seat as well as the back can freely oscillate independently I of one another, since they are not connected. On

the other hand, shocks and vibrations afiecting the back and seat are directly transmitted by them to the base members 1'7, 1'? where they are stopped without having an opportunity of being propagated from one part to the other.

I claim:--

A chair comprising a unitary metal tube bent to form a rectangular frame, one end of said frame being bent up vertically to form the rear supportsand the back, the opposite end of said frame being bent up vertically to a predetermined degree to form front supports and then bent horizontally towards the back to form the seat, the

central portion of said frame connecting said front and rear supports while retaining its original position and thus forming a base for the chair.
